lhils application ls a continuatn-in-part of my application of the sametitle led July 20, 1943, Serial No. 495,476.

The invention relates Ato valves, especially to a valve ofthe typewherein the body or bonnet is provided with a yoke supported bearing forthe outer end of the valve stem and a packing gland for'such valve stemarranged between the arms of the yoke and adapted for repacking, withoutdismounting of the valve parts, by provision of a removable followermember, and it is particularly directed to means for supporting thefollower member when removed from the gland for re-l packing, especiallywhen such follower member .haga separable follower flange member, sothat the follower member and flange mmber will not interfere with orobstruct the work or replacing or renewing the packing in the gland.

In packing glands of the type referred to, where in a separable flangemember is provided for pressure-boltlng the follower member to the valvebody or bonnet, while at the sametime accommodating imequal applicationof pressure, it is customary for the follower member and flange y memberto have complementa] mating surfaces .replacing or renewing ofthepacking in the gland.

The object of the invention is t0 provide means for retaining the glandfollower ange member in supported released position for repacking of thegland and for coupling thegland follower member to the follower flangemember in such a manner that these two parts may be handled individually or as a unit, as desired, so that the re- Fig. 3 is anenlarged perspective view of the gland follower ange member of thelinvention, in one preferred form.

The parts of the valve, including the body l,

, bonnet 2, gate I, stem l, yoke 5, hand wheel 6,

packing operation may be materially simplifled, v

gland l, gland follower` I, gland follower ilangve member I, andclamping bolts Ill with their nuts ll, are, in the main, of conventionalform, but the arms I2, l! of the yoke, and the gland follower member laregland follower flange! aremodified in the matter of variousstructural details to adapt them to the practice of the invention.

follower ange member 8 are provided with conventional mating sphericalsurfaces I3 and Il. respectively, thus making pressure-bolting of thefollower possible without binding regardless of uneven pressure appliedby the bolts i0 and nuts I l. However, despite the advantages inherentin this and other forms of separatevcooperating gland follower membersand follower flange As shown, the gland followervmember ll and,

ment.

2 y merrrtere,- they have the Adisadvantage that when they are withdrawnfor repacking of the gland they will separate, and, although thefollower flange member may be supported out of the way of packingoperations, the follower member it self will tend to slide back into thegland and is thus an inconvenience. l

In accordance with the invention, the follower. flange member isprovided with diametrically arranged ears I offset or displaced at anangle with respect to the longitudinal axis through the bolt holes I6,and the arms I2 of the yoke i are provided with inwardly offstandinglugs I1, it being noted that the under surfaces IB of the ears I5 andthe upper surfaces I9 of the lugs I1 are of a form serving forcomplemental interengagement, preferably of arcuate form. Thus when thefollower flange member is withdrawn from the gland along the valve stem4 to a position above the lugs I1, as shown in Fig. 6, and rotated 3ative' rocking and sliding movement longitu'dlnalthrough an angle equalto that of the displacement of the ears I5, substantiallyas shown inFig. 7, and released so that its ears' I5 will come to rest upon thelugs I1, these complemental surfaces' I8 and I9 will interact to holdthe follower flange member flrmlysupported and effectively blockedagainst rotation upon the vvalve stem I.

In order that the gland follower member B may be withdrawn from thegland 1 alongwith the ly of the follower ange member 9' by virtue of.the spherical contour of the mating surfaces Il land Il.

To this end the follower flange member I'ls recessed at its lower faceto provide a rimv 28 normally extending below the ostanding lip 2l ofthe follower. member, and preferablyA in notches 29-provided indlametrically opposite portlons'of the lip 28 are arranged finger means,secured by welding, as shown, or otherwise appropriately fastened to theange. These nngers extend from the flange zlradially inwardly'so as'tounl derlie the. lip l23,' of the followermember to'an extent sufficientto prevent inadvertent-complete axial separation of the follower memberand follower ilange member, vbutsumcient separal tion is provided toaccommodate the parts tothe relative axial, rotative and oscillatorymovement l necessary for their effective functioning;

'Ihe form.

with Figs. 1 to 7.

The operation of the from the foregoing, but in `the interest of fclearness, and asis apparentfrom 'an inspection of Figs. 4 to 7, it willbe seen that when the pressurebolting nuts II are removed, the glandfollower member 8 or 8' may be 'withdrawn with the follower flangemember 9 or 9 fromthe gland'l, andj when the flange' member is elevated'above the L lugs Il of the yoke'arms |2'andpartially' rotated, l

as shownin Figs. 5 and?, and already described,

y it may be relatively 'immovably supported by enable U-shaped hookmember2ll'pivotally retained I in a bore 2| in the follower flangemember, one

leg 22 thereof extending below the flange member and capableA ofengagement 'with or disengagement from an offstanding annular lip 23 onthe gland follower 'member 8, and, the votherleg overlying `the flangemember and vnormally riding upon a cam track 25 having adjacent to oneend e.

a seat 26 and adjacent to itsotherv end a stop member 2l.

'I'he leg 24 of the hook member 20 will, n ormally, when the gland'parts are in operative as" sembly, .be retained in the seat 2B of thecam track (see Figs'. 1 and a) and the leg 2z thus held from engagementwith the Vannularlip 23 of the gland follower. However, whenvit isdesired to connect the gland follower with Athe vfollower flange member,so that the two may vbe'handled asa unitary assembly, it is merely`necessary to rotate the leg 24 through approximately 90'.thuspositioning the leg 22 below the lip 23, the leg 24 thus assuming arelatively xed position be? t tween the end of thev cam track 2 5 andthe stop vmember2l (see Figs. 4 and 6) y With this'mode of connection,it willi-be seen *that the'follower member B and follower flange member9 are capable of being handled as separate parts, or they may beinterconnected and handled as allnit.
